McAfee SIEM and ASM

I am trying to integrate McAfee SIEM and F5 ASM 11.2.1. However, the SIEM doesn't parse the logs correctly. After raising a ticket with McAfee, they said the issue is with the log format which is sending ';' as a delimiter instead of '|'. ASM is managed by customer's 3rd party and they have been interesting to deal with.

Below is the snippet of the logs, could you please confirm if the logging format is correct and if we can change the delimiter to '|'
